Is fiber optic cable fragile?

- The test was just a simple test. I didn't use the OTDR in this video. OTDR can tell us much more about the quality of the cables after those tests.
The glass fiber within the cable is fragile and, although the cable has been designed to protect the fiber, it can be damaged more easily than a copper wire. The most common damage is a broken fiber, which is difficult to detect. But fibers can also be cracked from too much tension during cable pulling or despooling.
What is the difference between single mode and multimode fiber?Single mode fiber has a smaller core than multimode and is suitable for long haul installations. Single mode systems are generally more expensive. Multimode fiber has a larger core and is recommended for fiber runs less than 400 m (1300 feet). ... Multimode systems are generally less expensive

Okay this makes me feel so much less paranoid about whether I'm gonna break them. Anxiety is gone and now I'm gonna share with people that need to know
I would like to see the resistance of these cables while exposed to 50c degree.
Thank you in advance for your valuable experiments.
Great video. kindly do test optical fiber cable which has thick sleeve, which used for ftth from junction box to home fiber optic cable
Even a fusion splices, with 60 mm protection sleeves are fairly strong - probably as strong as the original cable! One tip when pulling fiber in metallic electrical conduit (that is, not designed specifically for fiber) -- LSZH jackets are much more abrasion resistant than PVC jackets. (I haven't tried OFNP jackets bec I cannot find a vendor with G657.A2 or tighter radius bend insensitive cable in OFNP -- can only find G657.A1 which has a larger bend radius and I feel a smaller bend radius is more preferable).
Thank you: this was exactly the video I was looking for!
cell phone providers made us use a 3 feet bend radius minimum. im curious what your DB readings would be with a couple or few hundred feet. also, we had most of our issues with the glass connectors. we had to scope every one, clean it and target it in a screen shot for a report of the fibers. every last fiber had to pass through its full length. i think they gave us 10db.. its been years
Interesting video.
I work in industry and I am faced with getting signals back from moving machinery, think like robot arms etc where there is repetitive movement. Using copper wire of the correct type (beryllium copper), failures were occurring every 5 years of so. After switching to fiber, the failure rate decreased to more than 10 years! Even then, it was not the fiber that failed, rather it was the sheath material, leaving the bare fiber intact.
Probably was unwanted noise or interference. Proper shielding copper might be OK too or fiber for sure.
does that apply to toslink too?
Toslink uses plastic cores so should handle bends better.
What if we have hydrogen gas or any magnets near to it?
Hydrogen gas can cause attenuation or loss of signal strength in fiber optic cables. Hydrogen molecules can penetrate the fiber optic cable's protective coatings and react with the glass fibers, causing them to become opaque or cloudy, which reduces the transmission of light. This phenomenon is known as hydrogen darkening or hydrogen-induced attenuation.
it's important to note that the effects of hydrogen gas and magnets on fiber optic signals depend on the strength and proximity of the gas or magnet to the fiber optic cable. In general, fiber optic cables are designed to be resistant to these types of interference, and they are often installed in protective conduits or sheaths to further reduce the risk of damage.
I got it. Thanks for the detailed and clear explanation. All the best your knowledge sharing channel and your best efforts.
